Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

Yield, quality characteristics, and composition of Limnanthes alba seed as affected by rate, source, and date of nitrogen application

Creator:: Ayres, Thomas Arthur
Abstract:: The effect of nitrogen (N) application on seed yield of Limnanthes alba was studied for two years at two locations. Seeding following alfalfa (Medicago sativa L.) was compared to establishment after wheat (Triticum aestivum L.). Treatments used were a control (no N applied), and two rates of N (50 and...

Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:: McCarthy, Michael J.
Abstract:: Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...

Nitrate reductase activity as a factor influencing the seasonal succession of marine phytoplankton

Creator:: Roelofs, Nancy Ann
Abstract:: Nitrate reductase is known to be the enzyme regulating the reduction of nitrate to nitrite in plants. This reduction is the first and rate-limiting step in the transformation of inorganic nitrate to a cellular nitrogen form. Since this reduction process is essential to phytoplankton growth when nitrate is the only...

The effects of light on photosynthesis and rooting of leafy cuttings of Pisum sativum L.

Creator:: Davis, Tim D.
Abstract:: The effects of light incident on leafy cuttings is quite complex because' light influences several factors which may affect root formation. One effect of light is to influence the carbohydrate status of the cutting by influencing photosynthesis. The role of current photosynthate in the rooting of leafy cuttings is uncertain....

The differential response of Fraxinus pennsylvanica, Liquidambar styraciflua, and Acer saccharinum to picloram as measured by CO₂ absorption and evolution

Creator:: Webb, Warren Lewis, 1935-
Abstract:: The tolerance of woody plants to picloram (4amino-3,5,6-trichloropicolinic acid) has been shown by field applications to vary from mild to extreme. A laboratory study was done to investigate the basic causes for this range of tolerance known to exist among three woody plant species, Fraxinus pennsylvanics, March, (green ash) resistant,...
